Abstract (en)
[origin: WO03032516A1] A method in a location enabled mobile wireless receiver having an oscillator, including determining a change in cellular network based frequency error of the oscillator (250), based on a difference (230) between a cellular network based frequency error of the oscillator and a reference cellular network based frequency error (210) of the oscillator, determining a first frequency error of the oscillator by summing (250) a reference satellite positioning system receiver based oscillator frequency error (220) with the change in cellular network based frequency error of the oscillator.
